Square box

Accessible by removing the front grille and terminal box cover, connection under plaster or cable on plaster. The terminal block includes a relief clip to prevent the cable from being pulled out.

Noise

emitted by the fan is measured at a distance of 1.5 m.

Mounting

is carried out on the wall using the paper mounting template supplied. Dowels and screws are also included. When the front grille is removed, the fan is automatically switched off by the built-in safety switch. During installation, we recommend flexible pads under the fan mounting points to reduce noise transmission through the building structure.

Instructions

Ventilators are suitable for relatively long ducts with higher pressure drop or for direct through-wall ventilation. The fans can be used for ventilation in residential construction, in conjunction with a HIG 2 hygrostat or with a hygrostat combined with a thermostat for ventilation of wet areas.
